It's either that, or we shoot 'em with a water gun.
Researchers plan to test a "gun" that shoots pulses of water at high velocity to determine if it could keep Asian carp from slipping into Lake Michigan.
Leon Carl is regional executive for the U.S. Geological Survey, and he talked about the technology at a public hearing Thursday.
Carl says the heavy cannon creates enough energy to deter or kill fish and could be mounted near a lock in Chicago - the point where some fear the carp could get into the lake by breaching an electrical barrier farther inland.
Nice to see people getting creative about this.
